KONe

KONe is a wall-mounted condensing boiler with very low polluting emissions, thus falling within the new Class 6, the most restrictive currently in force. It is available in instant combined version.


KONe has all the “Quality Stars” to satisfy every type of need:

  • Exceptional modulation ratio up to 1:8 Efficiency >107% (ex CE dir. 92/42) ηs 93% (EU regulation 813/2013 - ERP dir. 2009/125/CE)
  • Energy class A
  • Ultra-flat Al/Si/Mg primary exchanger
  • Electronics with HWS “Hot Water Speed” function (vers. C)
  • Low NOx class 6 (according to EN 15502-1) thanks to the completely electronic modulating premix burner with constant combustion ratio (both gas valve and fan)
  • Production of hot water up to 13.3 l/min Dt 25 with special exchanger with 12 plates (mod. 24 C) and 16 plates (mod. 28/35 C) in AISI 316L stainless steel
  • “Pit stop” maintenance for technical assistance interventions
  • “Soft touch” control panel with protective closure “Upgradable” via USB connection for diagnostics/programming with computer or dedicated handheld tool
  • High efficiency modulating circulator
  • HWS “Hot Water Speed” is the special KONe electronics that switches from the heating to domestic hot water function with the burner and pump always active, improving the comfort of the user who does not have to wait for hot water. Management of 2 zones with 2 thermostats (modulating/on -off) thanks to the electronics which allows you to manage 2 heating zones at different temperatures (high for radiators and fan-coils, low for radiant panel systems)
  • Sliding temperature programmed to operate with the lowest possible flow temperature to promote energy saving
  • Post-circulation anti-overheating, the boiler automatically keeps the pump running for 5 minutes after the burner is turned off, preserving the components
  • Chimney sweep function allows maintenance workers to carry out the checks required by current regulations regarding performance and emissions
  • Pump anti-blocking, blocking of the pump following long stops is avoided thanks to an automatic 5 sec impulse.

Everything like in a “Sim Card”

All the operating characteristics of the boiler are stored inside a SIM. The Unical Assistance Center is equipped with a handheld instrument with a 3" touchscreen, which can be connected directly to KONe to develop the monitoring activity, speeding up intervention times for the resolution of any problems: data acquisition for computer analysis monitoring in real-time operating parameters even remotely (from the office or PDA) management of "faults-history"

“Pit stop” maintenance in less than 2 minutes

KONe is the result of the Service's experience and market suggestions, from which the Unical design staff has synthesized a technological complex that can be easily assembled and quickly dismantled.
